Description

一种建筑物雨水收集与生态利用系统 技术领域
本发明属于雨水再利用技术领域，特别是涉及一种建筑物雨水收集与生态利用系统。
背景技术
海绵城市，是新一代城市雨洪管理概念，是指城市在适应环境变化和应对雨水带来的自然灾害等方面具有良好的“弹性”，也可称之为“水弹性城市”。国际通用术语为“低影响开发雨水系统构建”。下雨时吸水、蓄水、渗水、净水，需要时将蓄存的水“释放”并加以利用。
初期降雨时，前2～5mm的雨水一般污染严重，流量也比较小。雨水溶解了空气中的大量酸性气体、汽车尾气、工厂废气等污染性气体，而且一般含有一定量的影响植物生长的毒素，这些毒素可能包括硫化物、盐分等，甚至不适当的pH值。降落地面后，又由于冲刷沥青油毡屋面等，使得前期雨水中含有大量的有机物、病原体、重金属、油脂、悬浮固体等污染物质，因此前期雨水的污染程度较高，通常超过了普通的城市污水的污染程度。如果将前期雨水直接排入自然承受水体，将会对水体造成非常严重的污染，也不能将雨水直接回收利用，所以必须对前期雨水进行弃流处理，可以设置雨污切换装置，将降雨初期雨水分流至污水管道，降雨后期污染程度较轻的雨水经过预处理截留水中的悬浮物、固体颗粒杂质、沉淀、过滤，就可以达到回收利用的标准。
目前，大部分弃流装置容积为所有初期雨水体积，容积过大；一些采用手动操作排放初期雨水的装置容易由于操作问题失效；而可以自动开关的容积虽然小，但构造复杂、成本高；另外，初期雨水停留时间过长，导致固体颗粒杂质沉淀，装置极易堵塞，不利于装置正常使用。
目前，屋面雨水收集方便，然而储存缺较为困难，在地下和建筑周围储存雨水，往往条件不允许。因采用落水管作为存水设备，不占地，不影响美观，且储水量大。然而也存在一系列难题，初期雨水的处理，以及一些固体垃圾的分离都是十分棘手的问题。弃流装置容积为所有初期雨水体积，容积过大；一些采用手动操作排放初期雨水的装置容易由于操作问题失效；而可以自动开关的容积虽然小，但构造复杂、成本高；另外，固体物容易进入到容器里，尤其具有固体颗粒，自动弃流初期污染雨水十分困难。
